With heavy resistance, back pad will need to be adjusted
to keep torso close to arm pad. Adjust seat height, so back of
upper arms rest on padding. If seat is too high, shoulder will
need to rise near end of extension to complete final range of
motion since forearms will make contact with pad before lockout.
If seat is too low, range of motion will be compromised because
elbows will not be completely flexed at beginning of movement.
If machine has secondary lever (as shown), elbows do not have
to be exactly aligned with primary fulcrum. Also see Lever
Triceps Extension on alternative apparatus.
